DescriptionBACKGROUND OF THE INVENTION
This invention relates to a voice-synthesizer timepiece capable of requesting and/or reciting time settings in the form of synthesized voices when in a time set mode.
A voice-synthesizer timepiece has already been proposed in U.S. Pat. No. 3,998,045, TALKING SOLID STATE TIMEPIECE, assigned to Camin Ind. However, no consideration was of audibly announcing time setting functions.
Accordingly, it is an object of the present invention to provide a voice-synthesizer timepiece capable of providing advance announcement before time setting is required and reciting time settings already entered, in the form of synthesizedvoices. For example, in a voice-synthesizer timepiece according to the present invention, an audible message "please set time in hours and minutes soon" is given in advance of a time set mode and time settings are audibly recalled in such a form as"X(in hours) and Y(in minutes) have already been set" after the setting of time.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a plan view of the outer appearance of a clock calculator for which the present invention is applied and FIGS. 2(A) and 2(B) are block diagrams showing principal circuit configuration of the clock calculator of FIG. 1. It is obvious tothose skilled in the art that the present invention is also equally applicable to any other types of timepieces such as solid state wristwatches.
There is illustrated a keyboard K, a keyboard encoder KE which converts signals entered via the keyboard K into corresponding codes, a program memory RU implemented with a well known read only memory, an address register RAR, an address decoderRDC, and instruction selection gates RUG. An instruction decoder IM is adapted to generate microinstructions 1 - n according to the contents of the program memory RU inputted via the instruction selection gates RUG. There are further provided a memoryunit RM consisting of a random access memory, an address counter AC, an address decoder AD, an input/output control circuit MS, an adder FA incrementing the address counter AC and a reset circuit CA for resetting the counter AC. An accumulator islabeled ACC, an input gate to the accumulator ACC is labeled GA, an output buffer is labeled BS1 and an input gate thereto is labeled GO.
A clock generator CG and a frequency divider DV generate time base signals for timekeeping. A seconds register TS, a minutes register TM and a hours register TH are further provided in relation with the divider DV. Although not shown in thedrawings, registers storing time or calender information in other units of time such as a date register and a month register may be provided. An input gate GT is provided for the minutes register TM and the hours register TH as well as an outputselection gate ST. A specific time detector JT senses if the contents of the seconds register TS and the minutes register TM reach 59 minutes and 50 seconds.
A memory unit VR of a read only memory storing sound quantizing data has an address counter VAC and an address decoder VAD. A reset circuit CLA resets the address counter VAC in order to inhibit the delivery of an audible output by failing tospecify any of the addresses of the memory unit VR. A subtractor SB decrements one of the address of the addresses counter VAC and, after an initial address has been set up in the address counter VAC for a desired one of voice regions P, executes theoperation of VAC-1→VAC automatically at a fixed sampling frequency, thus fetching the sound quantizing data in sequence from that region P. The memory unit VR is provided with an output gate G. An END code detector JE is adapted to sense an ENDcode located at the final step of the respective regions P and provide an output for rendering the reset circuit CLA operative to reset the address counter VAC. A reset state detector JZ senses if the address counter VAC is in the reset state and isconnected to the instruction selection gate RUG together with the outputs as denoted as S2 of the END code detector JE and the specific time detector JT and so forth.
A code converter CC receives voice region identifying signals S1 supplied from the output buffer BS1 and converts initial addresses of selected ones of the voice regions P into codes compatible with the address counter VAC. A flip-flopF controls the output gate G of the memory unit VR. The code converter CC supplies a reset signal GR when the voice region identifying signal S1 is received and supplies a set signal GS otherwise, thereby setting and resetting the flip-flop F. Theoutput gate G is enabled with the flip-flop F in the reset state.
In the drawings, a digital-to-analog converter is labeled DAC, a low pass filter LPF. a speaker driver DD and a loud speaker SP.
Operation of the above device will be described by reference to a flow chart of FIG. 3. The step n0 is executed to decide if any key input has been entered and selects any of the steps n1, n2, n3, n4, n5 . . . foridentifying the type of an actuated key. For example, if a digit key N is identified during the step n5, then the step n6 decides if a flip-flop FS1 is in the set state and if negative the next step n7 is reached so that the keyinput is treated as an input to the calculator.
The step n3 senses the presence of an actuated time set key TIME.SET and if so the step n8 becomes operative to generate the micro-instruction 3 and set a flip-flop FS. As will be described later, the flip-flop FS1 is set. Upon the actuation of the digit key N subsequent to that of the time set key TIME.SET the step n6 perceives the flip-flop FS1 in the set state, followed by the step n9 wherein the micro-instruction 15 is developed to load the instantaneousinput into the accumulator ACC. The step n1 decides if a hours unit selection key HO is depressed and if affirmative the step n10 follows wherein the microinstruction 19 is developed to transfer the contents of the accumulator ACC intothe register TH. Thereafter, the step n11 is executed to generate the micro-instruction 24 and set a flip-flop FH. The step n2, on the other hand, is to sense if a minutes unit selection key Mi is actuated, followed by the step n12,when the affirmative answer is given, wherein the micro-instruction 23 is developed to unload the accumulator ACC into the minutes register TM and the next succeeding step n13 wherein the micro-instruction 25 is developed to set a flip-flop FM.
The time set mode is initiated upon the actuation of the time set key TIME.SET and any desired time is set after a succession of the actuations of the digit keys N, the hours unit selection key HO and the minutes selection key MO .
When the time set key TIME.SET is actuated, the step n14 is executed to generate the micro-instruction 11 and set a flip flop FL and the step n15 senses the flip flop FL in the set state, followed by the steps n16→n17 → for monitoring the operating states of the respective flip flops. In this case, since the flip flop FS has been set upon the actuation of the time set key TIME.SET , the step n17 results in the affirmative answer asto the flip flop FS, rendering the step n22 operative to monitor the set state of the flip-flop FS1. If the flip-flop FS1 is not in the set state, then the step n23 is executed to transfer a series of the word data LS fromthe program memory RU to the memory unit RM.
As depicted in FIG. 4, the word data LS has a chain of the word data in which m1 generates the micro-instruction 13 to reset the address counter AC and m2 -m14 send a the word date of "tadaima kara ji fun wo settei shimasu(its English version is "please set time in hours and minutes soon") including pause codes Pa to the program memory RM. This transferring procedure is carried out as shown in a flow chart of FIG. 5. P1 generates the micro-instruction 15 andtransfers the word data (e.g., "tadaima" in m2) from the program memory RU into the accumulator ACC. Subsequently, P2 generates themicro-instruction 22 for transference into the memory unit RM. In order to lead the next succeeding word data(the pause code Pa2 in m3 in the illustrated example) into the next address, the micro-instruction 14 is developed to increment one the address. If the word data LS are completely transferred into the memory unit, the step advances towardn.sub. 24 and n25 wherein the microinstructions 4 and 7 are respectively developed to reset the flip-flop FS and set the flip-flop FS1.
Then, the step n26 is effected to generate the micro-instruction 12 and reset the flip-flop Fu, followed by the step n27 which is a voice output routine as shown in FIG. 6. This includes O1 for generating themicro-instruction 13 and resetting the address counter AC, O2 for generating the micro-instruction 16 and transferring the word data from the memory unit RM into the accumulator ACC, O3 for deciding if a signal S2 has been developed and inother words whether the address counter VAC is reset or whether the END code detector JE senses the presence of the END code. When the signal S2 is outputted, O4 is reached where the micro-instruction 18 is developed to transfer the word datafrom the accumulator ACC into the output buffer BS1. This step allows audible outputs corresponding to the word data to be delivered later. While the audible outputs are delivered, the above mentioned signal S2 is not developed and the nextsucceeding word data remain stored in the accumulator ACC. O5 develops the micro-instruction 14 , increments the address counter AC and specifies the read-out position for the next succeeding word data. O6 decides if the address counter ACreaches "O". O2 -O5 are repeatedly executed until the overall regions of the illustrated example, the contents of the memory unit RM includes the steps up to m14 to complete the delivery of the advance announcement "please set time inhours and minutes soon".
Upon the delivery of the advance announcement the step n0 is returned and ready for the subsequent actuation of any key. If the hours unit selection key HO is actuated subsequent to the actuation of the digit key N, then the stepn18 is effected to decide if the flip-flop FH is in the set state, through the steps n14 and n15. The step n28 is carried out to transfer word data LH into the memory unit RU. The word data LH, as indicated in FIG. 4,include""X" ji wo settei shimashita, tadaimakara fun wo settei shimasu" (its English version if "time X in hours has been set and please set time in minutes soon"). The transmission of the hours information TH, i.e. the process m2 for LH iscarried out in the following manner as depicted in a flow chart of FIG. 7.
q1 is effected to generate the micro-instruction 17 and transfer the contents of the hours counter TH or the minutes counter TM into the accumulator ACC. When the hours unit selection key HO is actuated, the output selection circuit STselects the hours counter TH side in response to the micro-instruction 21 and "hours" information as decided by the digit keys N and the hours unit selection key HO is sent to the accumulator ACC. q2 generates the micro-instruction 22 andunloads the accumulator ACC into the memory unit RU. The next step q3 develops the micro-instruction 14 and increments the address counter AC.
When the word data including the "hours" information TH are transferred into the memory unit RM in this manner, the step n29 is reached where the flip-flop FH is reset, followed by the steps n26 →n27. The step n27for the delivery of an audible message "time X in hours has been set and time in minutes is about to be set."
Since the step n19 is effected to decide the set state of the flip-flop FM upon the actuation of the minutes unit selection key Mi , the step n30 is carried out to transfer word data LM into the memory unit RM. By way ofexample, FIG. 4 shows the word data LM "time TM in minutes has been set." The "minutes" information TM is carried out in m2 as indicated in FIG. 7. When this occurs, the output selection circuit ST responds to the micro-instruction 20 forselection of the minutes register TM side. After the word data LM have been loaded into the memory unit RM in this manner, the step n31 is at work to develop the micro-instruction 27 and reset the flip-flop FM, followed by n26→n27. During the step n27 an audible message "time TM in minutes has been set" is delivered to the operator.
When the time set key TIME.SET is actuated under these circumstances, the steps n17 →n22 are executed and the step n32 is reached because of the flip flop FS1 in the set state. The step n32 transfers the word dataLS1 into the memory unit RM. In other words, as indicated in FIG. 14, the word data LS1 "time in hours (TH) and minutes (TM) has been set" are transferred and delivered during the step n27. The n33 stands behind the step n32and develops the micro-instructions 4 and 8 and resets the flip flops FS and FS1, thus completing the time set mode.
Provided that the actuation of a time recall key TK (the tough switch type in FIG. 1) is sensed by the step n4, the step n32 is effected to generate the micro-instruction useful in setting a flip flop FT. That set state is sensedby the step n20 and the step n33 transfers word data LT into the memory unit RM, which word data are audibly delivered through the step n27. For example, a message "it is now TH in hours and TM in minutes" indicative of theinstantaneous time when the time recall key TK is actuated. The step n34 generates the micro-instruction 6 and resets the flip flop FT.
If any key is not actuated, the steps n0 →n35 →n15 →n10 → . . . are repeated and the specific time detector JT senses "59 minutes 50 seconds" each hour and makes the steps n36 →n14operative. During the step n36 the micro-instruction 1 is developed and the flip-flop FJ is set. During n14 the flip-flop FL is set. Accordingly, a chain of the steps n15 →n16 →n37 →n38 arepracticed. The step n37 develops the micro-instruction 2 and resets the flip-flop FJ, whereas the step n38 transfers word data LJ into the memory unit RM. As indicated in FIG. 4, the word data LJ carry a message "tadaima karaTH ji rei fun wo oshirase shimasu, pu, pu, pu, puhn" (its English version is "this is to announce that it is now TH hours 00 minutes, peep, peep, peep, peep"). The "hours" information TH in m6 is transferred while the "hours" information from thehours register TH is incremented by one. The correct time comes when the last monotone is released. The step n27 delivers this message.
The pause codes Pa1, Pa2 and so forth shown in FIG. 4 are silent data and useful in appropriately dividing the messages and controlling the full length of the messages.
Whereas the present invention has been described with respect to specific embodiments thereof, it will be understood that various changes and modifications will be suggested to one skilled in the art, and it is intended to encompass such changesand modifications as fall within the scope of the appended claims.
